Jefferson, CA would still be California. The movement is
to make a new state out of counties in Northern California.
Jefferson is the working name of that movement. My
preference would be to keep the name California and allow
the southern portion of the former California to be
named North Mexico which seems to suit a majority of
the citizens. All conservatives from what was once SoCal
or the Inland Empire would be welcome in the low
tax/low regulation new state of California. However,
they would be stronly encouraged to leave behind all
traces of Dodger blue.
From wat I reaal of the map, the one I saw went down the east and included san diego county. i would call it East california although Jefferson would not be a problem.
